RESUMO
Certain Abruptex alleles in the Notch pseudoallelic series of Drosophila melanogaster show strong negative complementation. Heterozygous combinations of some viable alleles are lethal. As a lethal system this is unique. Analysis of this type of allelic interaction in gynandromorphs suggests that the lethal focus has a fate-map site in the anterior part of the fly, probably close to the central part of the thorax. In addition to the lethal effect, negative interaction of the alleles can also be seen in the morphogenesis of wings and chaetae of thorax and head. At this morphological level, the negative interaction of the alleles appears to be autonomous.
